Abu Salama reported: I heard 'A'isha (Allah be pleased with her) as saying: I had to complete some of the fasts of Ramadan, but I could not do it but during the month of Sha'ban due to my duties to the Messenger of Allah (ﷺ) or with the Messenger of Allah (ﷺ).

This hadith is narrated on the authority of Yahya b. Sa'id with the same chain of transmitters but with this variation that he said that ('A'isha did not observe fast but in Sha'ban) out of regard for the Messenger of Allah (ﷺ).

In another version of the previous hadith, the words are:" Yahya said: I think it was due to the regard for the Messenger of Allah (ﷺ)."

This hadith is reported on the authority of Yahya with the same chain of transmitters but no mention is made of the duty to the Messenger of Allah (ﷺ).

'A'isha reported: If one amongst us had to break fasts (of Ramadan due to natural reasons, i. e. menses) during the life of the Messenger of Allah (ﷺ) she could not find it possible to complete them so long she had been in the presence of Allah's Messenger (ﷺ) till Sha'ban commenced.

'A'isha (Allah be pleased with her) reported Allah's Messenger (ﷺ) as saying: If anyone dies in a state (that he had to complete) some fasts, his heir must fast on his behalf.

Ibn 'Abbas (Allah be pleased with both of them) reported: A woman came to the Messenger of Allah (ﷺ) and said: My mother has died, and fasts of a month are due from her. Thereupon he said: Don't you see that if debt was due from her, would you not pay it? She said: Yes (I would pay on her behalf). Thereupon he said: The debt of Allah deserves its payment more than (the payment of anyone else).

Ibn 'Abbas (Allah be pleased with them) reported: A man came to the Messenger of Allah (ﷺ) and said: Messenger of Allah, my mother has died (in a state) that she had to observe fasts of a month (of Ramadan). Should I complete (them) on her behalf? thereupon he (the Holy Prophet) said: Would you not pay the debt if your mother had died (without paying it)? He said: Yes. He (the Holy Prophet) said: The debt of Allah deserves more that it should he paid.

This hadith has been narrated on the authority of Ibn 'Abbas (Allah be pleased with them) from the Messenger of Allah (ﷺ).

Ibn Abbas (Allah be pleased with them) reported: A woman came to the Messenger of Allah (ﷺ) and said: Messenger of Allah, my mother has died and there is due from her a fast of vow; should I fast on her behalf? Thereupon he said: You see that if your mother had died in debt, would it not have been paid on her behalf? She said: Yes. He (the Holy Prophet) said: Then observe fast on behalf of your mother.

Abdullah b. Buraida (Allah be pleased with him) reported on the authority of his father: When we were sitting with the Messenger of Allah (ﷺ), a woman came to him and said: I had gifted to my mother a maid-servant, and now she (the mother) has died. Thereupon he (the Holy Prophet) said: There is a definite reward for you and she (the maid-servant) has been returned to you as an inheritance. She (that woman) again said: Fasts of a month (of Ramadan) are due upon her; should I observe them on her behalf? He (the Holy Prophet) said: Observe fasts on her behalf. She (again) said: She did not perform Hajj, should I perform it on her behalf? He (the Holy Prophet) said: Perform Hajj on her behalf.

'Abdullah b. Buraida (Allah be pleased with him) reported on the authority of his father: I was sitting with the Messenger of Allah (ﷺ) ; the rest of the hadith is the same but with this variation that the (the narrator) said:" Fasts of two months."

Ibn Buraida (Allah be pleased with him) reported on the authority of his father: A woman came to the Messenger of Allah (ﷺ), and the rest of the hadith is the same, but he said:" Fasting of one month."

Buraida (Allah be pleased with him) reported a similar hadith on the authority of his father that a woman came to the Messenger of Allah (ﷺ) and he said:" Fasting for one month."

Abu Huraira (Allah be pleased with him) reported Allah's Messenger (ﷺ) as saying: If any one of you is invited to a meal when he is fasting, he should say:" I am fasting."

Abu Huraira (Allah be pleased with him) reported: When any one of you gets up in the morning in the state of fasting, he should neither use obscene language nor do any act of ignorance. And if anyone slanders him or quarrels with him, he should say:" I am fasting, I am fasting."

Abu Huraira reported Allah's Messenger (ﷺ) as saying: Allah, the Majestic and the Exalted, said: Every act of the son of Adam is for him except fasting. It is done for My sake, and I will give a reward for it. By Allah in Whose Hand is the life of Muhammad, the breath of the observer of fast is sweeter to Allah than the fragrance of musk.

Abu Huraira reported Allah's Messenger (ﷺ) as saying: Fasting is a shield.

Abu Huraira reported Allah's Messenger (ﷺ) as saying: Allah the Exalted and Majestic said: Every act of the son of Adam is for him, except fasting. It is (exclusively) meant for Me and I (alone) will reward it. Fasting is a shield. When any one of you is fasting on a day, he should neither indulge in obscene language, nor raise the voice; or if anyone reviles him or tries to quarrel with him he should say: I am a person fasting. By Him, in Whose Hand is the life of Muhammad, the breath of the observer of fast is sweeter to Allah on the Day of judgment than the fragrance of musk. The one who fasts has two (occasions) of joy, one when he breaks the fast he is glad with the breaking of (the fast) and one when he meets his Lord he is glad with his fast.

Abu Huraira (Allah be pleased with him) reported Allah's Messenger (ﷺ) as saying: Every (good) deed of the son of Adam would be multiplied, a good deed receiving a tenfold to seven hundredfold reward. Allah, the Exalted and Majestic, has said: With the exception of fasting, for it is done for Me and I will give a reward for it, for one abandons his passion and food for My sake. There are two occasions of joy for one who fasts, joy when he breaks it, and joy when he meets his Lord, and the breath (of an observer of fast) is sweeter to Allah than the fragrance of musk.
